This is a sliding bedroom mirror door with a cracked plastic roller.
Each roller housing has one retaining screw. With that removed, the housing slides freely but in grooves, so can't just be pulled out.
I removed the door frame screws hoping to be able to lift the frame edge (top of the photo) out of the way so I could slide the roller housings out, but no luck. It doesn't lift up and wouldn't slide out of the way either.
So how do I get the roller housings out?
